TITLE OF THE INVENTION
DEODORIZER
BACKGROUND OF THE INDENTION
(Field of the Invention)
The present invention relates to a deodorizer which is safe for
human bodies, as well as foods, feeds, buccal compositions and aerosol
compositions containing such a deodorizer. '
(Description of the Prior Art)
As recent advancement in quality of life proceeds, the problem
of bad smell originated from individual bodies such as foul breath
and body smell has become a matter of great concern. Such a problem
has greatly affected even personal relations. Thus, there have been
proposed a variety of mouth wash liquids for removing or preventing
foul breath. However, most of these mouth wash liquids often contain
ingredients undesirable for internal use and the use thereof is
restricted to the deodorization of mouth.
On the other hand, there have already been proposed those which
make use of components present in foods, while taking safety thereof
into consideration. For instance, the following substances are known
to be effective as deodorizers: green tea extract (see Japanese Patent
Un-examined Publication (hereunder referred to as "J.P. KOKAI") No.
Sho 60-185558); red beetroot, cacao beans, coffee beans and parsley
extracts (J. P. KOKAI No. Sho 60-20'7664); perilla extract (J. P. KOKAI
1
~~08~~~
No. Sho 60-214726); persimmon extract (J. P. KOKAI No. Sho 61-87562);
butterburr plant extract (J. P. KOKAI No. Sho 61-206448); laver (J. P.
KOKAI No. Sho 62-152463); and finely ground material of bracket fungus
of the genus Fomes (J. P. KOKAI No. Sho 62-181048).
As~other deodorizers effectively used in the field of foods,
there have simply been proposed dimethylaminosulfonate, glucosamine
(J.P. KOKAI No. Sho 48-23946), cyclodextrin (J.P. KOKAI No. Sho 55
122700), organic acids such as ~ -ascorbic acid, benzoic acid,
gluconic acid, folic acid and nicotinic acid and salts thereof (J: P.
KOKAI No. Sho 60-136506).
However, all of these compounds can never prevent giving out of
bad smell, discharged from the inside of the body after any foods are
internally taken, such as bad smell of a belch eructed after eating a
dumpling stuffed with minced pork, bad smell of urine discharged after
drinking alcoholic drinks and bad smell of feces discharged after
taking meat.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a
deodorizer capable of oral intake, which prevents bad smell of
environment or foul breath, which can also be used in foods or
drinking to prevent giving out of bad smell emitted from cookings such
as those containing garlic and leek as well as cooked fish, which can
prevents giving out of bad smell after taking such cookings, and
which can be involved in metabolism to thus suppress the giving out of
bad smell from urine and feces discharged after eating and drinking
2
~oos~~~
such foods giving out bad smell.
A further object of the present invention is to provide foods,
feeds, buccal composition and aerosol compositions containing the
deodorizer.
The foregoing objects can effectively be achieved by providing a
deodorizer comprising a hydrophilic solvent extract of fruit-bodies
of champignon mushroom (technical name: Agaricus Bisporus) or powder
of the extract as an effective component.
According to another aspect of the present invention, there'~is
provided a food, a feed, a buccal composition or an aerosol
composition containing the hydrophilic solvent extract of champignon
mushroom or powder of the extract.
DETAILED EXPLANATION OF THE INVENTION
The present invention will hereinafter be described in more
detail.
There have already been known deodorizers obtained from
Hymenomycetes (see J.P. KOKAI No. Sho 62-181048), but Sho 62-1810u8
principally aims at the use of the fruit-body per se of mushrooms
which grow on wood such as bracket fungus of the genus Fomes as an
adsorbent but does not aim at the use of extracts derived from soft
edible mushrooms which are designed to be suitable for oral intake.
The effective components of the fruit-bodies of champignon
mushroom varies depending on the degree of mature and portions from
which the components are extracted. To obtain the extract of the
present invention, it is preferred to properly determine the time for
3
2~D083~~~
harvesting the fruit-bodies of champignon mushroom or alternatively to
change the method for extracting depending on the portions thereof to
be extracted.
In addition, the mycelium in compost also includes the effective
components, but products favorable for oral intake cannot be obtained
from the mycelium for the reasons, for instance, that the efficiency
of extract thereof is very low and that a large amount of contaminants
originated from the compost are mingled in the products during
extraction processes. '
The fruit-body of champignon mushroom which is usually used for
food is one in the course of growth and whose cap has not yet
completely grown (closed cap). In the present invention, it is
likewise preferred to use the fruit-body harvested at this time from
the viewpoint of coloring. Portions of the fruit-body to be used are
not restricted to specific ones, but the use of cap portion thereof
is particularly preferred in the invention.
The extraction of effective components from the fruit-body of
champignon mushroom is preferably carried out by cutting, into thin
pieces, fresh one which has not yet caused browning or those frozen or
freeze-dried when they are still fresh and introducing the sliced
pieces of the fruit-body into a hot solvent for extraction
immediately after cutting. The cut mushroom immediately causes
browning due to the action of phenoloxidase which in turn leads to
the decomposition of the effective components. Tt is also effective
for preventing such browning to treat the fruit-body by immersing in
or spraying with an orgnic or inorganic acid solution having a
4
~Ofl~34~
concentration of not less than 0.1%.
On the other hand, the mature mushroom having an open cap can
also be employed in the invention and it can be immersed in cold water
for 10 minutes to one hour to thus extract effective components from
dark purple spores and gills of the fruit-body. The extract is
initially colored deep purple and causes aggregation or precipitation
if it is allowed to stand at a cold place over night to give a clear
liquid. This liquid is inferior in thermal stability and, therefore,
it is preferred to store and use the same after freezing and drying
to obtain the desired effective components in the form of powder.
As solvents for extraction, there may be used, for instance,
hydrophilic solvents such as methanol, ethanol, isopropyl alcohol,
acetone and mixture thereof in addition to water. However, water
and/or ethanol are particularly preferred because they do not exert
any adverse effect on foods containing them. The weight ratio of
water to ethanol preferably ranges from 20/80 to 80/20 when a mixture
of water and ethanol is employed. The solvent for extraction is in
general added to the raw material in an amount ranging from 2 to 10
times (by weight) per unit weight of the latter. The extraction is
preferably performed at 60 to 100° C for 15 minutes to 2 hours, more
preferably at 80 to 95° C for 30 minutes to one hour.
The extraction is preferably carried out using a mixture of
water and an alcohol or acetone rather than using an alcohol or
acetone separately. In this case, the weight ratio of water to an
alcohol or acetone preferably ranges from 20/80 to 80/20.
Moreover, an organic acid or a sugar component may be added to
5
~Q08~4~
the solvent for extraction whereby the extraction of the effective
components can be performed efficiently.
Preferred examples of such organic acids include citric acid,
ma.lic acid, acetic acid and ascorbic acid. The amount of these organic
S acids ranges from 0.05 to 2% by weight on the basis of the total
weight of the solvent used whereby a pH value of the extraction
solvent is adjusted to 3.0 to 5Ø
Examples of the sugar components used in the invention are fruit
sugar, glucose, sucrose and maltose. The amount thereof added to the
extraction solvent desirably ranges from 0.5 to 5% by weight on the
basis of the total weight of the solvent. In this case, the effective
components present in the cell wall of the fruit-body can effectively
be extracted by the action of a high osmotic pressure due to the
presence of such sugar components.
Alternatively, it is also possible to perform such extraction
after adding 0.01 to 0.1% by weight of cellulase or amylase to water
and carrying out a reaction at 25 to b0° C for 2 to 2u hours to
decompose the cell wall or proteins. Furthermore, the mushroom is
I
first frozen and then thawed to destruct tissues (cell wall) whereby
the effective components can efficiently be extracted.
In the present invention, the fruit-body of the mushroom can
previously be lyophilized and then extracted.
The reason why the product of the present invention can prevent
giving out of bad smell and can show deodorization effect through
metabolism has not yet clearly elucidated, but it is thought that
polyhydric phenols, amino acid type compounds, minerals, in particular
6
zoos~~~
iron or copper ions, polysaccharides, and other components present in
the extract are involved in the deodorization mechanism.
The mushroom contains a lot of polyhydric phenols. This is
evidenced by the fact that the mushroom causes browning faster than
oi~her Hymenomycetes. In addition, it further comprises a large amount
of. proteins and free amino acids. Further, the content of iron and
copper thereof are also high. Therefore, it is assumed that the
mushroom is particularly effective for deodorizing mercaptans.
It has widely been known~that many polysaccharides having
specific physiological activity are generally present in Hymenomycetes
in a small amount. Likewise, it is believed that unknown components
included in the mushroom exerts influence on the metabolism of
alcohol in liver or on the enteric bacteria to thus prevent giving out
of bad smell.
The liquid extracted from the fruit-body of champignon mushroom
or the extract per se may be used as the deodorizer of the present
invention. Alternatively, they can further be processed and seasoned
or flavored to add them to various drinks, solutions or aerosol
preparations; or the extract is lyophilized to form powder of the
effective components. Thus, the powder can be incorporated into a
variety of basic materials to obtain various foods such as chewing
gums, candy and sprinkled foods, feeds such as foods for pets and
buccal compositions such as tooth paste and an agent for washing and
preventing giving out of bad smell from false teeth. In addition, it
can be taken in combination with other drugs such as a medicine for
the stomach and bowels in the form of a liquid, powder or tablets, or
7
further it may be incorporated into these drugs.
Dimethyl ether (DME) or the like are preferred as propellants
for aerosol compositions.
The amount of the deodorizer of the present invention to be
incorporated into a variety of basic materials is not restricted to a
specific level, but it in general ranges from 0.01 to 5% by weight
(solid content), preferably 0.1 to 3% by weight (solid content) based
on the weight of the material.
The present invention will hereunder be explained in more detail
with reference to the following non-limitative working Examples and
Preparation Examples.

As seen from the results listed in Table XIII, the products
obtained in Examples 8 and 9 show excellent deodorizing effect
compared with the control.
In Examples 8 and 9, hydrophilic solvents other than ethanol
such as isopropyl alcohol or acetone may be used, but ethanol is
2 G
~. ~oo~~~~
preferred because of its non-toxicity and its smell.
As the propellants, LPG and Freon (trade name) may be used in
addition to DME, but DME is preferred from the viewpoint of its
compatibility with water. Moreover, carbon dioxide gas or compressed
air may also be employed as a propellant.
The deodorizers of the present invention are safe since they
comprise extracts obtained from edible mushrooms and they are capable
of oral intake. Therefore, they can suppress foul breath by drinking,
chewing or licking the deodorizer of the invention. In addition, they
can be absorbed in the body and exert influence on the alcohol
metabolism to thus reduce the bad smell of the urine due to the
generation of aldehydes or to reduce the smell of feces as evidenced
by the experiments of the food for pet. Such specific effects have
not been achieved by conventional deodorizers for environment.
Moreover, the deodorizer of the present invention is excellent
in deodorizing substances which give out bad smell such as ammonia,
trimethylamine, hydrogen sulfide, methyl mercaptan, acetaldehyde and
formalin. Therefore, the products of the present invention can widely
be applied as deodorizers for environment such as those for
deodorizing kitchen waste, a lavatory, the interior of a room and the
inside of a car, as well as a factory and a cattle shed.
